My invention relates to improvements in sampling machines in which a movable cone with splitters and receptive openings for bulk mate- 1 Claim. (Cl. i3-421.)

rial operate in conjunction with a Xed cone with splitters and receptivevopenings for bulk materials; and the objects of my improvement are, rst, to provide a homogeneous separation of bulk material; second, to afford facilities for the adjustment oi the cones and splitters; and thirdA to remove from a bulk material a predetermined homogeneous amount.

I attain these objects by mechanism illustrated in thev accompanying drawing, in which- Fig, 1 is a longitudinal sectional View of the splitting machine; Fig. 2 is a vertical sectional view of the movable cone with attached splitters; Fig. 3 is a vertical sectional view of the fixed cone and attached splitters; and Fig. 4 is a sectional View ci the splitters taken along the line 5 4 in Fig. l.

Similar numerals refer to similar parts throughout the several views.

In Fig. 1, there is secured to the round container I the round container top 2 and the funnel base 3; and the discharge pipe 2 is secured to the funnel base 3 at the hole 5 in the funnel base 3. In the center of the round container top 2 is the round hole B and secured to the edge 'I of the round hole 6 is the top funnel 8. The upper hollow movable cone 9 has its apex I0 in the center of the round hole S. To the left hand edges II, II, II, II of the angular holes I2, I2, I2, I2 in the upper hollow movable cone 9 are secured the movable splitters I3, I3, I3, I3 and equally spaced one from the other, and the height of each of the angular holes I2, I2, I2, I2 on the upper hollow movable cone 9 is equal to the length of each of the movable splitters I 3, I 3, I3, I3 and the length of each of the angular holes I2, I2, I2, I2 is equal to one-half of the distance between two movable splitters I3, I3 in sequence. The degree of angle of the surface Ill of the upper hollow movable cone 9 with the horizontal is iifty degrees, and the upper edges I5, I5, I5, I of the movable splitters I3, I3, I3, I3 are at fifty degree angle to the surface IQ.

In Fig. 2. on the inside of the upper hollow movable cone 9 is secured the disc I6 near the apex I0; and the disc I6 supports the upper hollow movable cone 9 on the round flat surface I'l (Fig. 3) of the xed hollow cone I8 (Fig. 3). The upper hollow movable cone 9 is just enough larger than the xed hollow cone I8 (Fig. 3) to have free movement thereon, and the upper hollow movable cone 9 is secured to the fixed hollow 2 cone I8 by the bolt I9 through the disc I6 and the secured support arm 20 in the fixed hollow cone I8; and the upper hollow movable cone 9 on the fixed hollow cone I8 is movable by the control rod 2l (Fig. l) secured to the upper hollow movable cone 9.

In the fixed hollow cone I8 are the angular holes 22, 22, 22, 22 of the same size, shape and spaced as the angular holes I2, I2, I2, I2, and to the right hand edges 23, 23, 23, 23 of the angular holes 22, 22, 22, 22 of the fixed hollow cone I8 are secured the fixed splitters 24, 24, 24, l2li that are of the same size and shape as the movable splitters I3, I3, I3, I3 and spaced on the fixed hollow cone I8 in the same manner from the right hand edges 23, 23, 23,23, and with the surface of the ixed hollow cone I8 having a fifty degree pitch with the horizontal and the ixed splitters 24, 24, 22, 24 set at a fifty degree angle with the surface of the fixed hollow cone I8. The angular holes I2, I2, I2, I2 in the upper hollow movable cone 9 overlap with the angular holes 22, 22, 22, 22 in the xed hollow cone I8 as the upper hollow movable cone 9 is moved on the fixed hollow cone I3, and the angular overlapping of the holes I2, I2, I2, I2, 22, 22. 22, 22 may be either decreased or increased by the movement, and the amount of overlapping of each 0f the angular holes I2, I2, I2, I2, 22, 22, 22, 22 determines the split to be taken from the bulk material, by the splitter sets I3-24, I3--2A., Iii-24, I3-24. The springs 25, 25, 25, 25 are secured to the edges 26, 26, 26, 26 on the movable splitters I3, I3, I3, I3 and as the upper hollow movable cone 9 is advanced by the control rod 2l the springs 25, 25, 25, 25 advance through the slots .21, 2l, 2l, 2'! in the fixed splitters 24, 24, 24, 24 and curl outward from the upper hollow movable cone 9 so as not to interfere with the movement of the bulk material, and at the same time to aid the bulk material to enter the angular holes Ill- 22, I2-22, I2-22, I222.

The bulk material enters the sampling machine through the top funnel 8 and moves down the surface Ill and the portion of the bulk material passing between the splitter sets I3-24, I324,

I3-22, Iii-2l. moves through the angular holesr and each machine reducing the split; and as A illustrated in Fig. 1, the split is reduced by the lower unit 29, and the apron 30 is secured to the hollow cone base 28 and prevents the bulk material falling off the upper hollow movable cone 9 of the lower unit 29; and the split of bulk material passing through the hollow cone base 28 moves on the lower unit :29 at its apexr3l and thereafter the movement of the split bulk material on the lower unit 29 is the same as the` movement of the bulk material first described, y and the split taken from the split bulk material moves into the storage bin pipe 32, and the remaining portion of the split bulk material into the funnel base 3.

The sampling machine may be used as a mixer of bulk 'material by the movement of the bulk materials to be mixed through the machine as described for splitting to the valve 33 that is operated 4by the control rod 34, and by the valve 33 the splits moves into the funnel base 3 with the bulk material passing off the machine, as described.

The spring 25, 25, 25, 25 is of spring steel, and is as wide as the left hand edge il of the movable splitter I3, and it is to assist the bulk material to enter the angular hole l2-22, |222, I2-22, l2-'22; and also the spring 25, 25, 25, 25 does not interfere with the gravity flow of the bulk material that passes to the right side of the angular` hole l2-22, l2-22, l2-22, l2-22.

The sampling machine may be constructed to "split from a bulk material any per cent desired, predetermined by the number of splitters per cone and the size of the angular holes in the cones and the number of cone units. As illustrated the splitters on each cone unit, when Wide open, will cut one-half of the bulk material from the whole; and when the splitters are one-half open they will cut one-fourth of the bulk material from the Whole.

I have found by experiment that the best results in the use of the sampling machine is obtained when the surface of the cone is at iifty degrees pitch and the splitters are set at fty degrees angle to the cone surface.

Ihave used an angular hole in the'cone, the described shape splitter and internal movement of the split for the purpose of illustrating my invention, and I do not limit myself as illustrated.

`I claim:

The combination, in a sampling machine, of a movable cone having spaced openings therein and a iiange on one edge of Yeach opening to form a splitter, a stationary cone having openings of the same configuration and correspondingly spaced as the openings in the movable cone and a ange on one edge of each opening to form a splitter, the splitters of the stationary cone being on the edges of the openings that are oppositely related to the edges of the openings on which the splitters on the lmovable cone are located, the movablev cone being seated on the stationary cone in a nested relationship with the splitters of the stationary cone extending through the openings of the movable cone, means to rotate the movable cone whereby the openings may be brought in and out of registration to vary the size thereof, a funnel for feeding material over the movable cone, the apex of the movable cone beingV centrally located atthe discharge opening of the funnel, and a receiver in the form of an inverted truncated cone located beneath the stationary cone to receive material discharged through the registered openings of the cones.
